Auricular Acupressure for Sleep Disorder Prevention in Breast Cancer

Auricular Acupressure with Vaccaria Seeds Participants in this group receive auricular acupressure using 2 mm Vaccaria seeds adhered to five specific auricular acupoints (TF4, CO15, Extra5, LO4, LO4) with 7 mm × 7 mm adhesive patches. Each session lasts 10-20 minutes, with seeds left in place for 5-7 days. A total of 12 weeks, along with standardized sleep hygiene education.

Participants in this group receive sham auricular acupressure using identical adhesive patches without Vaccaria seeds, applied to the same five auricular points. Procedures, duration, frequency, and sleep hygiene education are identical to those in the experimental group to maintain blinding.
